Description

Technical Field

[0001] This utility model relates to the field of intelligent lock clutch technology, and in particular to an intelligent lock clutch device with a limiting structure. Background Technology

[0002] Smart locks are locks that differ from traditional mechanical locks, offering greater intelligence in user identification, security, and management. With the continuous improvement of people's living standards and the rapid development of the tourism industry, apartments and hotels have become part of people's accommodation choices for living and traveling. Currently, smart locks specifically designed for apartments and hotels, where occupants frequently change and settings need to be frequently modified, have emerged. Specifically, due to the design of the internal locking and unlocking structure of these smart locks, the outer door handle must be restricted to turning downwards to unlock, while the inner door handle can be turned downwards or upwards to lock or unlock. Therefore, existing smart lock clutch devices must have complex limiting structures.

[0003] Currently, no technical solution has been found to solve the above problems. In view of this, it is necessary to improve the current smart lock clutch device. Utility Model Content

[0004] The purpose of this utility model is to solve one of the problems existing in the related technology, especially to a certain extent the technical problem of the complex setting of the limit structure in the existing intelligent lock clutch device, and to provide an intelligent lock clutch device with a limit structure.

[0005] The above objective is achieved through the following technical solution:

[0006] A smart lock clutch device with a limiting structure includes a base plate, a shaft hole on the base plate, an outer door handle connector that can rotate around the shaft hole, an inner connector on one side of the outer door handle connector that passes through the base plate, the inner connector that rotates around the outer door handle connector, a rotation reset mechanism between the outer door handle connector and the inner connector, and a rotating member that is fixedly disposed with the outer door handle connector and can rotate with it, and a limiting part on the base plate for limiting the rotation stroke of the rotating member;

[0007] The rotational stroke of the rotating component is limited by the limiting part, so that the outer door handle connector can only rotate downward in one direction. When the rotating component stops rotating, the rotation reset mechanism will abut against the rotating component to reset it.

[0008] The inner connecting member rotates downward or upward around the outer door handle connecting member as an axis. When the inner connecting member stops rotating, the rotation reset mechanism abuts against the inner connecting member to reset it.

[0009] Furthermore, the rotational reset mechanism is a reset spring.

[0010] Furthermore, one end of the outer door handle connector is provided with a cylinder, and one end of the inner connector is provided with a circular groove that matches the cylinder and can rotate around it.

[0011] Furthermore, the substrate is provided with a stop block that cooperates with the rotation reset mechanism to allow the rotation reset mechanism to reset after rotation, the inner connecting member is provided with an inner rotation abutting arm that abuts against the rotation reset mechanism when it rotates, and the rotating member is provided with a rotation abutting arm that abuts against the rotation reset mechanism when it rotates.

[0012] Furthermore, there are two stops, which are respectively disposed on both sides of the base plate, so that the rotation reset mechanism can be rotated clockwise or counterclockwise to reset.

[0013] There are two inner rotating abutment arms, symmetrically arranged on both sides of the inner connector;

[0014] There are two rotating abutment arms, symmetrically arranged on both sides of the rotating component.

[0015] Furthermore, the limiting part is a protrusion block, which is located on the left or right side of the shaft hole. When the rotating member rotates, the rotating abutment arm will collide with the protrusion block to limit the movement.

[0016] Furthermore, the limiting part and the substrate are either integrally formed or separate parts.

[0017] Furthermore, the limiting part and the substrate are integrally stamped and formed.

[0018] Furthermore, the base plate is provided with a clutch drive device, the inner connecting member is provided with a clutch post that can slide up and down, and the rotating member is provided with a clutch notch into which the clutch post can extend. When the clutch drive device drives the clutch post to slide upward, the clutch post extends into the clutch notch. At this time, rotating the outer door handle connecting member causes the rotating member to rotate, thereby driving the inner connecting member to rotate.

[0019] Furthermore, the clutch drive device includes a drive motor and a U-shaped push block, the U-shaped push block being slidably connected to the clutch column, and the inner connecting member is also provided with a square rod connecting hole.

[0033] The following will provide a more detailed description of the composition, technical problems solved, and beneficial effects of this application, in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0034] Please see Figures 1-7 This application discloses an intelligent lock clutch device with a limiting structure, including a base plate 1. The base plate 1 is provided with a shaft hole 11. An outer door handle connector 2 that can rotate around the shaft hole 11 is provided on the shaft hole 11. An inner connector 3 is provided on one side of the outer door handle connector 2 that passes through the base plate 1. The inner connector 3 rotates around the outer door handle connector 2. A rotation reset mechanism 4 and a rotating member 5 that can rotate with the outer door handle connector 2 are provided between the outer door handle connector 2 and the inner connector 3. A limiting part 6 is provided on the base plate 1 to limit the rotation stroke of the rotating member 5.

[0035] The rotation stroke of the rotating component 5 is limited by the limiting part 6, so that the outer door handle connector 2 can only rotate downward in one direction. When the rotating component 5 stops rotating, the rotation reset mechanism 4 will abut against the rotating component 5 to reset it.

[0036] The inner connecting piece 3 rotates downward or upward around the outer door handle connecting piece 2. When the inner connecting piece 3 stops rotating, the rotation reset mechanism 4 abuts against the inner connecting piece 3 to reset it.

[0037] Its advantages lie in the fact that by providing a rotation reset mechanism between the outer door handle connector and the inner connector, and a rotating component that can rotate with the outer door handle connector, and by providing a limiting part on the base plate to limit the rotation stroke of the rotating component, the rotating component and the inner connector can have different rotation strokes while achieving rotation reset. The structure is ingenious, the limiting and reset are highly reliable, there is no need to set a complex limiting structure, and the overall size can be reduced.

[0038] Preferably, the rotational reset mechanism 4 is a reset spring.

[0039] Please see Figure 3 , Figure 6 In a specific embodiment of this utility model, one end of the outer door handle connector 2 is provided with a cylinder 21, and one end of the inner connector 3 is provided with a circular groove 31 that matches the cylinder 21 and can rotate around it. Its advantages lie in its ingenious structural design, high reliability of rotation, and smaller overall size.

[0040] In a specific embodiment of this utility model, the base plate 1 is provided with a stop block 12 that cooperates with the rotation reset mechanism 4 to allow the rotation reset mechanism 4 to reset after rotation. The inner connecting member 3 is provided with an inner rotation abutting arm 32 that abuts against the rotation reset mechanism 4 when it rotates. The rotating member 5 is provided with a rotation abutting arm 51 that abuts against the rotation reset mechanism 4 when it rotates.

[0041] Preferably, there are two stops 12, respectively disposed on both sides of the base plate 1, so that the rotation reset mechanism 4 can be reset by clockwise or counterclockwise rotation; there are two inner rotating abutment arms 32, symmetrically disposed on both sides of the inner connecting member 3; there are two rotating abutment arms 51, symmetrically disposed on both sides of the rotating member 5. Its advantage lies in its ingenious and reliable design, which facilitates reset after clockwise or counterclockwise rotation.

[0042] To better limit the rotational stroke of the rotating component 5, the limiting part 6 is a protrusion located on the left or right side of the shaft hole 11. When the rotating component 5 rotates, the rotating abutment arm 51 will collide with the protrusion to limit its movement. Its advantages lie in its reasonable structural design, convenient manufacturing, and ingenious limiting structure, allowing the overall size of the clutch to be made smaller.

[0043] In specific embodiments of this application, the limiting part 6 and the substrate 1 are either integrally formed or separate. Preferably, the limiting part 6 and the substrate 1 are integrally stamped. In practical applications, the substrate 1 is a metal part, and the protrusion can be integrally stamped and protruded from the substrate 1. Its advantages lie in its reasonable structural design. By integrating the limiting part with the substrate, the limiting part can be positioned at different locations on the substrate according to usage requirements. Manufacturing is convenient; it only requires adjusting the stamping position on a stamping press. The process is mature and highly reliable. Please refer to [link to relevant documentation]. Figures 8-9 The above configuration can better meet the left-opening or right-opening rotation limit when applied to smart door locks. The limit structure is cleverly designed, and at the same time, the overall size of the clutch can be made smaller.

[0044] Please see Figure 6In a specific embodiment of this application, the base plate 1 is provided with a clutch drive device 7, the inner connecting member 3 is provided with a clutch post 33 that can slide up and down, and the rotating member 5 is provided with a clutch notch 52 into which the clutch post 33 can extend. When the clutch drive device 7 drives the clutch post 33 to slide upward, the clutch post 33 extends into the clutch notch 52. At this time, rotating the outer door handle connecting member 2 causes the rotating member 5 to rotate, thereby driving the inner connecting member 3 to rotate. Preferably, the clutch drive device 7 includes a drive motor and a U-shaped push block. The U-shaped push block is slidably connected to the clutch post 33, and the inner connecting member 3 is also provided with a square rod connecting hole 34. Its advantage is that the clutch structure has high reliability. In actual application, a square rod (not shown in the figure) is installed on the square rod connecting hole 34. The square rod passes through the lock body (not shown in the figure) and connects to the inner door handle (not shown in the figure). Rotation of the inner connecting member 3 drives the square rod to rotate, and rotation of the square rod drives the lock tongue on the lock body to move and unlock.
